This very interesting 14 minute video demonstrates the functionality as well as the effectiveness of Germany's infantry weapons during WWII. Listed is a description of the Karabiner 98K, MP40 Machine Pistole, the famous Luger, the Stielhandgranate or better known as the Potato masher both MG34 and MG42 machine guns and more.

The video appears to be a vintage color film that was probably used for training purposes between 1939-1945 (unconfirmed)
